Auzzy,
Don't miss the fact that some of this area reverts to Class C under Dublin's control when not active.
And regarding MATZ, I'm planning on flying to Manchester Barton and wanted to have an idea of how much a challenge Valley/Mona may be? And of course to find out a MATZ's "trasitibilty" (just completely made that up ) and would it cause any routing problems.
I'm not sure where you are flying from, but I'm based at Weston. I'm happy to meet up some time and help answer any question you have on planning this trip. It's all very easy, but can seem somewhat daunting if it's your first one abroad
